Abstract
The invention discloses a kind of software development process reliability pre-detection method.Comprise the steps：Step one, reliability data collect, software reliability data collect before need to set up software error report, analysis and corrective action, in software test procedure is carried out accurate recording software test procedure, write software error report, software reliability data collect；Step 2, carries out software reliability prediction by prediction model of software reliability.The present invention is by carrying out reliability detection to software development process, there is defect in prevention software development process, improve the accuracy of software system data transmission and conversion, improve the accuracy of software development, reduce the construction cycle, and reduce software later stage run-time error and cause service failure rate.
Description
Technical field
The invention belongs to technical field of software development, more particularly to a kind of software development process reliability pre-detection side
Method.
Background technology
Generally software system reliability evaluation and software reliability prediction are software reliability detection essential elements.By number
Learn statistical method to calculate fail data and judge the reliability evaluation of software system, by known software reliability model and warp
Testing carries out software system reliability prediction.|input paramete of the fail data as reliability evaluation model, obtains model parameter, and
Software system measurement technology is carried out using the model parameter.Can pass through under known failure data qualification in software design procedure
Software reliability model carries out software reliability prediction, can then pass through in software development process under the conditions of unknown fail data
Related data is determined software reliability.For software system reliability prediction can be divided into early prediction and reliability is pre-
Survey, it is the Predicting Technique in software development process that early prediction master plays, and reliability prediction is mainly by software reliability mould
Type is tested.
In early prediction model due to not considering the growth of reliability and not setting up software reliability model and conduct static state
Measurement standard, is not set up the software reliability model of time-based module.
Content of the invention
It is an object of the invention to provide a kind of software development process reliability pre-detection method, by software development
Cheng Jinhang reliabilities detect occur the accurate of defect, the transmission of raising software system data and conversion in prevention software development process
Property, the accuracy of software development is improved, is reduced the construction cycle, and reduced software later stage run-time error and cause service failure
Rate.
The present invention is achieved by the following technical solutions：
The present invention is a kind of software development process reliability pre-detection method, comprises the steps：
Step one, reliability data are collected；
Step 2, carries out software reliability prediction by prediction model of software reliability.
Preferably, in the step one, reliability data is used for collecting out-of-service time data, actual effect data interval time, divides
The mobile phone of the cumulative failure number in group data, packet time.
Preferably, the concrete steps of software reliability prediction are carried out by prediction model of software reliability in the step 2
For：
Step one, by the reliability data for obtaining by assuming that fault model, estimation are with reference to acquisition model of fit；
Step 2, is fitted goodness inspection by obtaining model of fit；If the goodness of fit is combined setting value, step is entered
Three；If the goodness of fit does not meet setting value, by supplementary data or replacing model, repeat step one；
Step 3, obtains performance metric, and decision system is issued.
The invention has the advantages that：
There is defect in prevention software development process, carries by carrying out reliability detection to software development process in the present invention
High software system data transmission and the accuracy of conversion, improve the accuracy of software development, reduce the construction cycle, and reduce soft
Part later stage run-time error and cause service failure rate.
Certainly, the arbitrary product for implementing the present invention is it is not absolutely required to while reaching all the above advantage.
